Battery connector with contact terminal having improved retaining force

A battery connector adapted to hold a battery, comprising:

• an insulative housing defining a receiving chamber which having a horizontal bottom;
• a first conductive contact comprising a retention portion retained in the periphery of the receiving chamber, a resilient portion extending in a horizontal direction from the retention portion and pivotal about an axis of the retention portion along a vertical direction, a hook portion extending from a distal end of the resilient portion, and a spring arm extending from a location adjacent the distal end of the resilient portion;
• and
• a second conductive contact disposed in the bottom and having a resilient contacting portion for electrically engaging with the battery;
• wherein, the hook portion adapted to elastically urge an upper corner of a battery received in the receiving chamber while the spring arm deformed with a distal end of the spring arm supported on a vertical wall of the insulative housing.
